Unique ADU Builds to Explore

At Sustainable Design Build, we believe every square foot of your property holds potential and the ability to become whatever you need. Accessory Dwelling Units or ADUs are a unique custom home construction project that unlocks a variety of uses and functionality for a home. These custom home buildings are versatile, high-value additions to your home that can serve far beyond traditional guest suites, family extensions, and rentals. ADUs in the last few years have become a growing focal point in the Denver neighborhoods – giving inspiration to homeowners to maximize their property’s functionality and value. With increasing access and policy changes in Denver, ADUs are becoming more available and affordable to build. With that, SDB has seen some very impressive pitches into what clients have envisioned for their very own Accessory Dwelling Units.

Beyond Normal ADU Builds

While ADUs are commonly built for multigenerational living or short-term rental income, their potential goes far beyond these typical applications. Our clients are increasingly showing interest in ADUs as purpose-driven spaces tailored to their passions, work, and wellness goals.

Here are some inspired and innovative ways to build an ADU:

Private Home Fitness Studio ADU Builds

Health and wellness go hand-in-hand with the place you call home. SDB has seen many interests from clients looking to convert some part of their homes into a fitness studio or at-home gym. These typically look like renovating a basement or even converting a garage space. Taking things a step further, some potential ADU homeowners look to build a detached garage ADU for their home. Where a two car garage is the base to living quarters above which functions as a fully equipped fitness studio complete with:

• A dedicated workout space for weights, cardio, and yoga
• A kitchenette for post-workout smoothies or quick meals
• A private sauna and steam room, perfect for relaxation and recovery
• Smart climate control and audio/visual systems for an immersive wellness experience

This project redefines what it means to “work out at home” and showcases just how transformative ADUs can be when aligned with a client’s lifestyle.

ADU Art Studio ADU Builds

Another interesting use that ADUs can provide is a private area designed specifically to help with a passion of creativity. Whether you’re an artist, musician, or craftsman  an ADU can provide a secluded retreat that is dedicated to help encourage that pursuit. Sustainable Design Build has worked with musicians who have requested soundproofing and treatment to artists who need the most optimal storage spaces for their tools and work. ADUs can be designed with all these considerations in mind to make ideal:

• Art Studios
• Music Recording Studios
• Home Offices and Drafting Rooms
• Work-from-home offices

Wellness Retreats and Hobby Havens ADU Builds

Sometimes keeping things simple and separated helps create a healthy balance at home. From meditation rooms and massage studios, to craft rooms and wine lounges (or gameday bars), an ADU can become anything you want it to be with the closeness of home – but not in your home. This is a very attractive aspect to homeowners who want the physical separation of their passions and interests from their actual homes. This provides a level of privacy that allows immersion to be more freely experienced. The best part about all of these ideas is that at its core an Accessory Dwelling Unit will still remain a separate living space that can be used as one sees fit. One day it’s a hobbyist’s retreat, the next it is short-term rental housing. The functions of an ADU are only limited to your imagination.
